RRIGA'IING SYSTEM.

T0 all whom it may concern.'

Be it known that l, NATHAN A. HEACOCK, a citizen-of the United States, residing at Sullivan. in the county of Moultrie and State of Illinois, have invented certain new and useful improvements in lrrigating Systems, of which the following is a specification.

' My inventiony relates to irrigating sys-v ternsand particularly to that class of irriygating system wherein supply pipes are used'to discharge water upon a field and a drain pipe used for carrying olf the water after it has done its work.

The primary object of my invention is to provide an' irrigating system particularly applicable to rice growing or the raising of like crops in which it is necessary to provide means vfor controlling the period during which water may be kept upon the land and controlling the depth thereof.

'A further object of my invention is 'to provide very simple means of the character stated whereby water may be let onto and drawn oft the land at will and whereby the height'of the water upon the land ymay be controlled.

A further object is to provide meanswhereby relatively small sections of a field may be flooded or drained as desired.

. Still another object is to provide means may be withdrawn from another obiect is to provide means whereby the inlet of sediment into the drain pipe'mav moved from time to time as convenient.

Still a further object is to so arrange the pipes of the system that water may be uniformly distributed to all parts of each small area or section ofthe field to which the irrigating system is to be applied.

A Other objects will appear in the course of the following description.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a plan view of an irrigating system constructed in accordance with my invention; Fig. 2 isza plan view of another arrangement of this irrigating system; Fig. fis a perspective view of a portion of one 'of the supply pipes and its discharge outlets Specification ofrLetters Patent.

partly broken away; Fig. 4; is a ragmentary section of the discharge pipe; Fig. 5 is a perspective viewaof the drain pipe and inlet thereto; Fig. 6 is a sectional view of the same; and Fig. 7 is a transverse section of the arrangement shown in Fig. 2.

Referring to-the drawings, A designates a portion Vof a iield inclined from li toward C so that the natural drainage of the land will be from B toward C. This field is laid oil" into relatively small sections o by means of dikes 2 which are disposed in approximately parallel relation and which extend in the direction of the incline of the land.

ln the arrangement shown in Fi 1 there is a distributing pipe 3 disposed across the upper end of the field and supported in any suitable manner. rlhis pipe is connected by means of branch 4 to a reservoir 5 of any suitable capacity, this reservoir being in turn connected to any suitable source of water. This source in the drawing is shown as a well designated 5a. rl`he pipe 3 may extend along the upper edge of a iield of any desired size and the pipe may be of any desired length. rl`he pipe is preferably made 0f drain tile sections, the sections being impervious to water. however, but being laid below ground 'as illustrated in Fig. 3. At intervals the sections of the pipe 3 are provided with laterally extcnding outlets or branches 6 which communicate each with a vertical pipe 7. rThis pipe 7 extends below the level of the pipe 3 and is closed at its lower end as at 8. The pipe 7 extends above Lthe ground and is then bent over as at 9, so as to discharge downward onto the ground from any suitable height. The discharge end 9 of the pipe is provided with any suitable valve whereby the discharge through the pipe may be controlled. The vvalve is designated 10 and is illustrated as in the form of an inverted cone disposed below the discharge end of the bend and having an upwardly extending handle or spindle 13. This valve is so constructed as to close or partly close the pipe, depending on the flow of water required. i

The portion 11 of the pipe 7 forms a sediment collecting trap, and in this trap is disposed a sediment collector consisting of a vessel 14 having a handle 14a. The pipe 7 is made in two sections so that the upper section 7 may be removed to permit the revoir 16 which in turn is connected by means of Vthe pipe 17 toa receiving reservoir 18.

eeh

The water received in the reservoir 18 may be'pumped or otherwise carried back into the reservoir 5 or otherwise removed. The reservoir 16v may also be provided with a discharge .outlet 19.

T he pipe 15 is-,connected at intervals to a plurality of upwardly extending'branch pipes 20 as illustrated in'Fig'. 6, these vertical pipes'20extending belowthe pipe 15 so as to form a trap 21 at the lower endet each pipe for the. purpose of catching' sediment. Within each pipe 2O is disposed the catch basin or vessel 22 provided with the handle 23. rIhe upper end of the pipe 20 is provided at its outlet end with a protector comprising a cylindrical screen 26 inserted in the 'upper end of the end of this sereen`26v has an imperforate head 27. Mounted on and restingv upon this head 27v is an outer cvlindrical screen 28 having an imperforate head 29. This screen 28 surrounds the screen 26 in spaced relation thereto. The purpose of' these screens is to protect the intake of the pipes 2O from trash, leaves, coarse sediment or like material which would tend to obstruct the pipes. Co-

acting with the screens 28 and 2G is a hollow drum or cover 30 which is imperforate and is adapted to beplaced over drical screen 28. The purpose of this drum is to prevent water from passing through the screened intakes until the field is to be drained. This drum lowered to control the water to suit the yexigencies of any particular time. There are of course to be as many` pipes 20 leading into the main drainage pipe 15 as there are sections a of the field to be irrigated. The flow of water from the reservoir 5 is to be controlled by means of a valve 31 so that the water may be entirely cut off from the pipe 3.and therefore from the land, or may be admitted to the pipe at will.

The operation of my invention will be obvious from what has gone before. In certain seasons of the year it is most desirable to of course, either the reservoir 5`may be drained entirely or the Valve 31 closed. In this case the natural drainage from the land will be received in the reservoir 16, and car ried 4from the sump or reservoir 16 to the pipe 20. The upper the cvlinshown in Fig. 1 the is to be raised and Fxtending downward field 1s a main supply ave the land entirely dry, and in this case,

reservoir 18 or let out through the outlet pipe 19. The water after lit has passed from drain pipe 15 to reservoir 16 in no case4 is returned to reservoir 18 unless wanted to be" used on the field again for irrigation.

l When it is desired to flood the land, the valve 3l is opened permitting the Water to flow from the reservoir 5 into the pipe 3 and thence to any one of the sections a, de-

pending upon the position of the several valves 10. If the valves -10 of'all of the pipes 7 are opened itis obvious that all ofv the sections will be flooded and that by controlling the respective valve the Water let' onto any particular .section a may7 be controlled. If the hoods or covers 30 are kept in place closing the outlets ,through the pipes 20, it is obvious that the water will graduallvrise between the dikes 2, that the land will ,be flooded and that this flooded condition of the sections may be kept as long as desired and that the height of thevwater may be regulated to any desired depth. It

is also obvious that the height of the Water may be increased at any time or decreased at any time and that thus the amount of,

water upon the land may be at all times ac-` curately controlle Y When it is desired to drain the land it is only necessary to lift one or more of the covers 30, whereupon one or more of the-.

those f The construction shown in Fig. 2 ha's theA same lprinciple as that previously described. In this adaptaticn of my system as in that field A is divided off into relatively small sections a by the transverse (likes 2, these (likes running parallel to the'inelination ef the landQthis inclina-` tion being from the part B to the part C. across one end of the n pipe 33 which is connected at intervals to longitudinally extending pipes or secondary supply/pipes 34l which extend parallel along the field. As illustrated there are three of these secondary supply pipes. Each of the secondary supply pipes is provided at intervals with the -upwardlv extending discharge pipes 7,.such

as are illustrated in Fig. 3 and heretofore` described. All of the secondary pipes 34' are connected to the drain pipe 40. which extends transversely of the pipes 34 and dis-y charges into reservoir or sump 16. Valves 40 are disposed atthe intersectionof the secondary reservoir or sump 1G is connected by means of' the return pipe 17 to the receiving reservoir 18, which is connected to the mainreserpipes 34: with the pipe 40. The

.u pipe i by any tions, or these pipes may yin the 'former case,

Voir, 5. Disposed lat the lowest portion of the eld and extending approximately parallel with the pipes 34 is the drain pipe 15, discharging into reservoir 16. This drain pipe is provided at a plurality of points with the inlet pipes 20, which extend up to the surface of the ground, -as previously de'- scribed, and are provided with screens 26 and 29, previously described and'adapted to be closed by means of the hoods or covers 30. The iiow of water through the main is controlled by means of the valve 31.

lt may here be noted that in both cases illustrated the mouths of the pipes 7 carried one. supply pipe are to be so located with relation to'the surface of the ground immediately beneath them that all ot' said mouths will be at the same distance 'from the sui-tace ofthe ground. in order to prevent the discharge ol water from the pipes 7 from tearing up the ground., may provide beneath the outlet ot each of the pipes 7 a receiving basin designated 50 having laterally disposedpipes 51. This receiving basin 50 and the pipes 5i lie upon the surface of the land. and water from the discharge pipe 7 is discharged into the basin which is open at its upper end while the pipes 5l carry the water to diii'erent portions of the same secbe used to carry water to one or more adiacent sections, that is, the sections being considered to be those portions of the land divided by dilres. This would dispense with a discharge pipe 7 for each section. l'n Fig. l l show half .of the sections being provided with the receiving basins 50 and' laterally disposed pipes 5l. the other sections not being provide with these basins andA pipes.

The discharge pipes 7 as shown in Figs. 2 and 7 are oi the same construction as the discharge pipes shown in Fig. 4 and made in two portions, the'upper portion being removable, the junction 'i'a being at a level with the ground. Under 1these circumstances the secondary pipes 34 may act as 'drainage pipes so as to thoroughly drain the land of water. Normally when the pipes 34 are actingr as discharge pipes` the valves 4:01 are closed, but when it is desired to drain the land thoroughly, the valves .40a are opened and the discharge sections Ta arehremoved and screen intakes such as shown iii Figs. 5 and 6 are placed within the upper portions' of thc vertical pipes 7 thus making a complete system of drainage.

r)The operation of tion shown in Fig. 2 is the same as that previously desc'bed for that shown in Fig.' l. The only differences are that water will -flow into the secondary pipes and be more evenly distributed over the sections a of the field, and

that these secondary pipes 34 may be used as drainage pipes as above described. As the flow of water onto between the supply *pipes of the sections 7 andthe form of the inven-k l have found that my improved system,y

oi irrigating is particularly valuable in rice planting, but it may be used1 for all crops .wherein it is nccessaryto retain water upon various periods.
